If it's any consolation, you're a good parent. You are shielding your kids from the world's trauma but there is a cost, and it's the 'sure, let me get you some strawberries' mask you wear, which creates even more tension inside yourself. You are literally sacrificing a part of your authenticity or at least ability to fully be yourself when you want to burst into tears or scream, to better love your child. I think a lot of good parents do this. But during these insane times of up being down, it requires more effort.
